I just bought a used 2006 vx110 with 24 hours on it. I checked the oil cold today sitting on the trailer, and its at the full line. From reading the forum, this sounds like way too much right? Should I just remove a bunch before even starting it to do routine maintenence/winterizing? I don't want the oil to leak into the air filter which I hear happens when there's too much oil. Thanks for the input.

Sounds like too much oil. When my FX is cold I can barely see oil on the dipstick.......I suspect the VX will be similar. Remove oil until its at the add mark on the dipstick cold. Run it on the hose for at least 10 minutes (or even better ride it for 10 minutes) and check the level right after you stop the engine (remember to turn off the water first if on a hose). If its on a trailer, be sure the ski (not necessarily the trailer) is level to get an accurate reading. I always shoot for a level 1/2 between the marks when the ski is hot, checked right after I have ridden it on the water, which will give you the most accruate reading.

Another question, this ski came with a motocross ytx20l-bs, my online research tells me this is sealed, does that mean there is no need or even a place to hookup the vent line?

Right, that is a motorcycle battery and there most likely will be no vent port.

I know many people that replace the Yamaha batteries with sealed batteries with no problems. I think the large compartment the battery sits in is well enough vented that there is no danger of build up of fumes, etc., and I'm not even sure if that is even an issue with sealed batteries. In fact, I've actually heard of problems with the vented batteries ruining the paint on skis if they do vent.

You should be good with a motorcycle battery, since they are usually designed for vibration. The mistake many make is getting a cheap battery that is not designed for vibration and they internally vibrate apart, and the owner is left scratching their head with a dead battery after only a short time.

So I ran it on the hose today and washed out the inside of the bilge and sprayed it down with some silicone spray. Since I've never really dealt with jet skis, should I just bring it to the shop and have them go over it and do like a 50 hour check up or something? It only has 25 hours, but it's a 2006 and they only did the 10 hour service. Or should I just go ride it and see what happens?

That ski is pretty much bullet proof. Unless you just have some cash burning a hole in your pocket, I'd say avoid the dealership, and just ride it. All the dealer will do is hook it up to a hose, run it for a few minutes, and shine a flashlight around inside and charge you $100 and tell you its good to go.

Since that ski has a dry sump oil system and only around 1/2 of the oil can be changed each time, its not a bad idea to change the oil at a more frequent interval than recommended (I think Yamaha says every 100 hours after the initial 10 hour change). If you plan to keep it for a while, I'd change out the oil every 50 hours or so.

Other thing to remember on that ski if it ever seems to start running bad, change the spark plugs as a first step.............a fouled spark plug can account for all sorts of weird running problems, and is not uncommon.

Too much Oil

My 2006 VX deluxe showed no oil after the winter layover so I topped to correct level, cold. I started the engine and it idled OK but when reved smoke went every where.

Upon checking oil again and after reading this forum no surprise, way too much oil. I have syphoned the excess out but could I have damaged the motor?

Also what happened if I leave the water running through the hose with the motor off, more damage?

No real damage to the motor with running it with overfilled oil, but you can foul the spark plugs, and damage the air filter, so check the filter to be sure it has no oil in it..........if it does replace. You should suck out the excess oil ASAP an get it to the correct level when the engine is hot.

You can definitely damage the engine by running the hose with the engine off. Water can be forced through an open exhaust port into the engine and cause a lot of damage..........even total the engine. Always start the engine before you start the water, and turn off the water before you stop the engine.

you start the ski for 10 seconds then check oil level
might want to read up on the owners manual
I'm guessing you meant 10 minutes rather than "10 seconds". The manual actually says to run the ski for a minimum of 6 minutes before checking the oil and for an additional 5 minutes (11 minutes total) if the air temperature is less than 68 degrees F.

I've found you get the most accurate reading after riding the ski for at least 15 minutes, then pull into a shallow area with the ski on the water where it will be perfectly level, get off the ski and check the oil immediately while the engine is hot. If you wait more than a few minutes the oil drains back into the engine and you will not get an accurate reading.

Problem Solved

Hey guys, by my readings, there are problems with your jetskis due to overfilled oil. Heres the solution, when there is too much oil, the oil tends to overflow into the air filter, thus, staining and clogging up the filter. This causes the Jet ski to not breathe. With that being said, the oil may end up going into your engine where the spark plugs will get stained. If so, you have to suck out the oil and either suck all of it out, or suck it out until its the correct level. After this has been done, go buy a new air filter because the previous one is more than likely stained and clogged due to the oil overflow. Third, if desired, may benefit if oil filter is currently dirty, go ahead and buy a new oil filter. Lastly, change the spark plugs. There is also another thing that you may want to do if after starting the PWC and smoke continues to come out, (it shouldnt.) perform a compression tests, this can be searched up on youtube, and you can take it from there. Hope I helped you guys, this is a common problem not a big deal. Best of luck guys.
ONE MORE THING, DO NOT START THE WATER BEFORE STARTING THE PWC! ALWAYS START THE JET SKI FIRST (CAN RUN FOR 15 SECONDS WITHOUT WATER BEFORE DAMAGE CONSISTS) THEN TURN ON THE WATER. Let me know if this works
